I figured I'd do a write up on my system since I had to reach from a number of resources to find all the answers I was looking for. This can also serve as a place for questions about my set-up if my details are lacking.
First, my purchase list. I'm reaching from memory here so it may not be totally complete. Lots of these things you can purchase from Lowes or homedepot except for a few that I point out.
Here is a crude paint drawling of the water lines. Red = hot and blue = cold:
The electrical is pretty simple and really depends on where you want to run wires. My switch for the pump is mounted on my drawers then runs through the firewall into the relay. The power come straight from the battery with a 10 amp fuse before reaching the relay. The power from the relay then runs straight to the pump with another 10 amp fuse inline. The relay, pump, and switch are grounded to the closest bolt.
Both of my quick disconnects were in the rear bumper (intake and output) but my intake line fell and got melted by cat underneath. I plan on rerouting it underneath and securing it with zip ties better. You need about 18' of hose to reach from the engine bay to the rear bumper. So 36' if you run the intake and output to the rear. You'll need another 5' or so for the lines that run between the helton, pump, T, mixer, etc. Then you need as much line as you desire to run for the sprayer and input.
These are the only photos I have right now, but will get better ones soon.
You will need to find a way to mount the pump. I made a very simple bracket by welding some 1" flat bar to make a mohnting surface. I'll get better photos of that later.
